HDAX-CBE-CPE-RCE 3-Inch Cat-Back Exhaust System

The MAPerformance HDAX-CBE-CPE-RCE catback exhaust system is engineered to elevate the performance and sound of the 2017-2021 Honda Civic Si Coupe. It utilizes a 3-inch diameter, 304-grade stainless steel construction, featuring mandrel-bent tubing throughout to minimize restrictions and turbulence for optimal exhaust gas flow. This design directly contributes to enhanced performance by reducing the energy required for gases to pass through the system. Quality is a cornerstone of this exhaust, with MAPerformance utilizing in-house fabrication and quality control. The tubing is mandrel-bent on a CNC-programmed bender, with each bend's accuracy measured. Expert fabricators TIG weld each flange and joint using back-purging to ensure long-lasting, leak-free welds. The use of 304 stainless steel, superior to the more common 409 stainless, resists surface rust and ensures longevity. One of the standout features is the user-configurable exhaust note. The system includes a resonated mid-section and offers interchangeable tip options (Street or Race) connected via a 3-inch V-band. The Street tip provides a moderate, deep tone suitable for daily driving and road trips, while the Race tip delivers a louder, more aggressive sound. Installation is facilitated by the inclusion of all necessary hardware. Additionally, the system is built with consideration for ground clearance, making it suitable for lowered vehicles. MAPerformance backs this exhaust with a Limited Lifetime Warranty on all in-house TIG-welded components.
